A Model of Habitability Within the Milky Way Galaxy [PDF]

open access: greenAstrobiology, 2011
We present a model of the Galactic Habitable Zone (GHZ), described in terms of the spatial and temporal dimensions of the Galaxy that may favour the development of complex life.

On the Spiral Structure of the Milky Way Galaxy [PDF]

open access: yesAstronomy Reports, 2010
We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e.

Chemodynamical simulations of the Milky Way galaxy [PDF]

open access: yesThe Astrophysical Journal, 2011
We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from oxygen to zinc.

Wormhole in the Milky Way galaxy with global monopole charge

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole.

The Mass of the Milky Way [PDF]

open access: yesThe Astrophysical Journal, 1996
We use the Jaffe model as a global mass distribution for the Galaxy and determine the circular velocity $v_c$ and the Jaffe radius $r_j$ using the satellites of the Galaxy, estimates of the local escape velocity of stars, the constraints imposed by the known rotation curve of the disk, and the Local Group timing model. The models include the systematic

The spiral structure of our Milky Way Galaxy [PDF]

open access: yes, 2009
The spiral structure of our Milky Way Galaxy is not yet known. HII regions and giant molecular clouds are the most prominent spiral tracers. We collected the spiral tracer data of our Milky Way from the literature, namely, HII regions and giant molecular

The Milky Way and other spiral galaxies [PDF]

open access: yesEPJ Web of Conferences, 2012
Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation.

Chemodynamical simulations of the Milky Way Galaxy [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractWe simulate the chemodynamical evolution of the Milky Way Galaxy, including the nucleosynthesis yields of hypernovae and a new progenitor model for Type Ia Supernovae (SNe Ia). In our nucleosynthesis yields of core-collapse supernovae, we use light curve and spectral fitting to individual supernovae to estimate the mass of the progenitor, the ...

In Pursuit of the Least Luminous Galaxies [PDF]

open access: yesAdvances in Astronomy, 2010
The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass

Microlensing Maps for the Milky Way Galaxy [PDF]

open access: yesThe Astrophysical Journal, 2002
At any instant, there are roughly 1000 ongoing microlensing events to sources brighter than 20th magnitude in the Milky Way Galaxy. Large-scale maps of the microlensing optical depth and the mean timescale are constructed for a number of models of the Galactic bar and disk, incorporating the effects of streaming and spiral structure.
